Materials Data on Tb2O3 by Materials Project
Abstract
Tb2O3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded to six O2- atoms to form a mixture of distorted corner and edge-sharing TbO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of Tb–O bond distances ranging from 2.22–2.50 Å. In the second Tb3+ site, Tb3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Tb–O bond distances ranging from 2.26–2.75 Å. In the third Tb3+ site, Tb3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Tb–O bond distances ranging from 2.26–2.61 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to six Tb3+ atoms to form OTb6 octahedra that share corners with six OTb4 tetrahedra, corners with two equivalent OTb4 trigonal pyramids, edges with two equivalent OTb6 octahedra, edges with four equivalent OTb5 square pyramids, and edges with six OTb4 tetrahedra. In the second O2- site, O2- is bonded to four Tb3+ atoms to form OTb4 tetrahedra that share corners with two equivalent OTb6 octahedra, corners with two equivalent OTb5more »
